Among the objects of this invention is the provision of mechanism for receiving a four unit numerical code over one wire and redistributing the characters in time phase to retransmit them over four wires; for furnishing suitable means for operating printers of a type similar to the well known stock ticker for monitoring and recording incoming line signals; for receiving at intervals a five unit coded signal for operating a special printer for the purpose of transmitting operating instructions; and for alternatingly transmitting information received as difierent channel information as predetermined by code signals received.-

Other objects of this invention will be ap parent to those skilled in the art after reading the following description taken in connection with the drawings, in which Figs. land 2 show a development in a plane of the receiving distributor and the storage relays for controlling both the monitor printer functions and the four wire retransmission; and

Fig. 3 shows a development in a plane of a four wire retransmitting distributor, together with various control rings and relays and the relay circuit used for operating the so-called monitor printers.

The mechanism disclosed for purposes of illustration includes a receiving distributor RD, Figs. 1 and 2, and a retransmitting distributor RTD, Fig. 3. The receiving distributor comprises a line receiving ring A having a start segment ST, a segmented ring 13. having hundreds, tens, units, MUX, range, and tens, units and fractions price segments, and a start segment, and segmented monitor printer controlling rings C and D, and a segmented operation controlling ring E, which will be referred to more specifically later, and a continuous grounded ring F. A brush arm, not disclosed, which carries brushes RBI and BB2 is adapted to be frictionally driven from a motor, not shown, when released by the start magnet SMl.

The retransmitting distributor RTD, Fig. 3, includes segmented rings G, H, I and J, which include start segment, channeling segment, hundreds, tens and units stock number segments, range segment, and tens, units and fractions price segments. The distributor RTD also includes a ring K having a segment later referred to, and a continuous grounded ring L. A brush arm, not shown, and having brushes indicated at TB, is adapted to rotate over these rings when released by the starting magnet SM2.

Both distributors are normally at rest with the respective brushes resting on the start segments. The incoming line L, controlling the receiving distributor, has a marking potential held on it during the time that the receiving distributor is at rest. When the start pulse is sent over the incoming line the armature of the line relay LR, Fig. 2, is thrown to the spacing contact S operating the receiving distributor start magnet SMl, over the start segment ST of the line receiving ring A, and the segmented ring B connected by the brush RBI. The brush arm is released and isrotated at any suitable speed and, as preferred in practice, at 102 rotations per minute.

In the course of a rotation the marking impulses of a four unit code are transmitted over the ring A and through the brush RBI, in suc cession over the segments HSN, TSN, USN, MUX, range, tens, units and fractions of the ring B. It will be noted that there are four segments -for each item of transmission, except the fractions segments of which there are three, and the MUX segments ofwhich there are five, a five unit code being transmitted over the MUX segments and a four unit code being transmitted over the remaining segments. The impulses transmitted over the MUX segments operate a multiplex (or MUX) printer which may be of any well known type, or other electrical recording device using a five unit code.

As the brush RBI is rotated, a marking impulse transmitted across the first of the HSN segments, marked 1, operates the relay HSNR, marked 1, which locks across its contact 10 and contact 11 of relay HUP, to ground. If ground is applied when the brush arm is in contact with the hundreds stock number segment, marked 2, the hundreds stock number relay, marked 2, will pull up and look over its contact 10 and overthe contact 11 of relay HUP, to ground. Whether or not the hundreds stock number relays marked 3 and 4 pick up depends upon whether ground is applied to the ring A as the brush passes over the segments 3 and 4.

In a like manner, when the ring A is grounded as the brush passes over the tens stock number segments, certain of the tens number relays 'TSNR, marked 1, 2, 3 and 4, will pick up and look over their contacts 12, and across a contact 13 of relay TUF, to ground. In the same manner, certain of the units stock number relays USNR, marked 1, 2, 3 and 4, will pick up and lock over their contacts 14, and contact 15 of relay TUF, to ground. The brush then passes over the MUX segments operating the MUX printer,

or other electrical recording device, after which the brush passes over the range, tens, units and fractions price segments, operating combinations of the range, tens, units and fractions relays designated RaR, TR, UR and FR, and bearing the small numerals 1, 2, 3 and 4. The range relays RaR lock over their contacts 16, and a contact 17 of the relay RTP, to ground. The tens relays TR lock over their contacts 18, and a contact 19 of the relay R'IP, to ground. The units relays UR look over their contadts 20, and a contact 21 of relay HUP, to ground. The fractions relays FR lock over their contacts 22, and a contact 23 of relay TUF, to ground. The four unit coded information as to the stocl designation, range, and tens, units and fractions prices. is now stored in the stock number, range and price relays in Figs. 1 and 2, these relays being held up over contacts of the relays RTP, HUP and TUF in combinations to release the range and tens price storage relays when the relay RTP is operated, the hundreds stock number and units price storage relays when the relay HUP is operated. and the tens stock number, units stock number, and fractions price when the relay TUF is'operated, as will be described later.

The storage relays in Figs. 1 and 2, in addition to the locking contacts, have two sets of contacts 25 and 26 associated respectively with the four wire distributor shown in Fig. 3, and with the monitor printing rings C and D of the receiving distributor, the latter contact 26 coding the information received to be transmitted to the monitor printing rings. Certain of these storage relays also include a third set of contacts 27, which will be referred to later.

The mechanism includes also a group of channeling and phasing relays, Fig. 3, which insure that a channel-one transmission will be made first when the mechanism starts from a position of rest. and that during a continuous series of operations, the channel-one and channel-two transmissions will 'be made alternately. This mechanism includes also a relay for channeling the information to a pair of monitor printers, as will be described later.

Four wire retransmitting distributor As the distributor brush BB2, Figs. 1 and 2, connects the segment 6 of the ring E, Fig. 1, to ground, over the ring F, the starting magnet SM2 for the four wire distributor R'ID, Fig. 3, releases the brush TB which moves over the respective distributor rings. The brush normally connects the grounded ring L to the segment tdr of the ring K energizing the relay TDR, which closes at its contact 28 the circuit for the phasing relay PH when the distributor brush BB2 of the receiving distributor is in its home position and connects ground on the segment 17 of the ring E to the grounded ring F. However, at the time that the transmitting distributor is released the phasing relay is unoperated and the relay CS is unoperated, so that as the brush TB passes over the channel segment CH of the ring J, ground will not be connected over the contact 29 of the relay CS and, therefore, there will be no ground out for the line 4 going to the master repeating relays. Ground will be transmitted over the channel segments CH of rings G, H and I across lines 1, 2 and 3 and cable 30 to the master repeating relays which transmit impulses controlling receiving mechanism, not shown, to receive the subsequently transmitted stock information as a channel-one information.

As the brush TB continues its movement it grounds the HSN segments of the rings G, H, I and J, applying ground to lines 1, 2, 3 and 4 which, as shown in Fig. 1, continues across the operated contacts 25 of the hundreds stock number relays to four lines which are cabled as at 30, and which are the lines that go to the master repeating relays, as indicated in Fig. 3, causing these relays'to operate and transmit a four unit code for the outgoing four wires.

As the brush moves over the tens segments TSN of the distributor rings G, H, I and J, ground is applied across these segments to lines 5, 6, 7 and 8 which, in Fig. 1, are shown as connected across the operated contacts 25 on the relays TSNR which areconnected to the four wires which go to the master repeating relays, causing these relays to operate and transmit a four unit code representing the tens stock number.

In a similar manner, as the brush TB moves over the units stock number segment USN, ground is applied to the lines 9, 10, 11 and 12 which are connected across operated contacts 25 of the units stock number storage relays USNR, Fig. l, to the four lines in cable-30 which extends to the master repeating relays.

In a similar manner, a four unit code is transmitted as to the range, tens, units and fractions prices as the brush TB moves over the segments R, T and U of the rings G, H, I and J, and the segments F of the rings H, I and J. As shown in Fig. 2, the four lines to which ground is applied over the contacts 25 of relays Ra, T, U and F are connected across break contacts of the relay BSN-2 to the four lines which go to the master repeating relays. The BSN2 relay is normally unoperated, as shown in Fig. 1. When the brush BB2 moves over the segment 5 of the ring E, ground is applied to one side of the winding of the relay BSN-1 which pulls up and at its contact 31 applies ground to a line which is connected across the contacts 27 of the hundreds stock number relays HSNR, when these relays are unoperated,'to line 28 which is connected to one side of the winding of the relay BSN2, causing this relay to pick up if no hundreds stock number has been received. This disconnects the four lines going from the range, tens, units and fractions storage relays from the four lines going to the master repeating relays, so that no information can be transmitetd in reference to range, tens, units and fractions prices in the case where no hundreds stock number has been received. BSN2 relay locks over its own contact 32, across a contact 33 of the relay RTP, Fig. 1, to ground, so that this condition will be maintained until the relay RTP is operated.

The monitor printer controlling rings C and D of the receiving distributor, Figs. 1 and 2, are arranged for overlapping the selection and price information to the two channel printers, the receiving line relays of which are indicated in Fig. 3 at CH-1R and CH-ZR, the printers being controlled from these relays in the usual manner. While the hundreds stock number, tens stock number, units stock number, and range, are successively printed on the channel-one monitor printer, the tens, unitsand fractions prices. of the preceding quotation are being printed on the channel-two monitor printer.

The monitor printers are arranged to operate with a start-stop system having a six unit code, the sixth pulse being supplied for the purpose of shifting the printing mechanism from upper to lower case. The type wheel used with the monitor printers, instead of printing the. usual stock abbreviation in the upper case, prints a three digit stock number. Each of the digits to be printed redufres a stop pulse to its associated monitor printer, and these stop pulses are supplied from separate segments located after the sixth interval of each character. The start pulses are supplied during the open interval to the monitor printer control relays during which time a spacing impulse is sent to, the control magnets of the respective printers.

As the brush-RB2, which is carried on the same brush arm as the receiving distributor brush RBI, moves over the rings C, D and E, it connects ground from the ring F to the various segments of the rings C, D and E. It is assumed here that the mechanism has been at rest for some time, and a stock number, range and price being received and transmitted that the channeling relay CH, Fig. 3, is deenergized so that the impulses as to the stock designation will go out over channel CH1 to the channel-one monitor printer.

As the brush BB2 connects ground on the ring F to the first segment of the ring C, ground is extended over the operated contact 26 of the hundreds stock number relay HSNR, marked 1, it this relay has been energized, to a line designated 19 which is connected to a line 1 connected to each of the SP segments of the ring C, and extended across a break contact 40 of the relay CH, Fig. 3, to the channel-one line CH-1 operating the relay CI-I--1R, Fig. 3.

In a similar manner, ground will be connected across the ring F and the segments 12,13 and 14 of the ring C, and through lines 2, 3, 4, across contacts 26 of the operated relays HSNR, marked 2, 3 and 4, and across the circuit before described to the monitor printer relay CH-IR.

As the brush RB2 continues its movement it connects ground to the stop segment SP to control the monitor printer controlled by the relay CH-lR.

In a similar manner, as the brush BB2 travels over the segments 21, 22, 23 and 24, impulses are transmitted over the contacts 26 of the operated relays TSNR to the monitor printing relay CH- 1B.

In the same manner information as to the units stock number and as to the range, is transmitted from ground on the ring F, over the segments 31, 32, 33 and 34; and 41, 42, 43 and 44, and across the contacts 26 of the relays USN'R and RaR to the relay CH--1R controlling the channel-one monitor printer to print the units stock number and the range.

As the brush BB2 passes over the segment 4 of the ring E, after the hundreds stock number has been transmitted, it operates the relay RTP which releases the range relays mm, the tens price relays TR, and the BSN-2 relay, if this relay was operated. As the brush RB2 moves over the segment 5 of the ring E it operates the BSN1 relay, which causes the BSN-2 relay to operate in case no stock number was set up. As the brush continues its movement across the segment 6 of ring E, it operates the start magnet SM2 for the four wire distributor, Fig. 3, causing this distributor to operate. As the brush moves on to segment 10, it completes the circuit for the relay HUP, Fig. 1, releasing the hundreds stock number storage relays HSNR, and the units price relays UR. As the brush grounds the segment 12 it sets the MUX printer in operation. As the brush grounds the segment 13 it closes the circuit for the relay TUF, Fig. 1, which releases the storage relays for the tens and units stock number relays TSNR and USNR, and the storage relays FRfor the fractions price.

After transmission of the hundreds, tens and units stock number, and the range, and the release of the holding relays, as described, the brush grounds the segment 46 of the ring C which operates the relay CH1R for controlling the case shifting mechanism in the channel-one monitor printer. As the brush continues its movement, ground is applied to the two stop segments SP of the ring C, and ground is also applied to the segments 16 and 17 of the ring E, the ground on the segment 16 being extended to the contact 41 cf the relayCR, Fig. 3, and the ground on the segment 17 being extended to the contact 28 of therelay TDR, Fig. 3. In a position of rest of both distributors, the relay TDR, Fig. 3, is operated from the segment tdr of the ring K, and ground over segment 17 of the ring E of the receiving distributor operates the phasing relay PH, which releases the channeling relays CS and CH if previously operated so that the first information transmitted at the beginning of a series of transmissions will go out over channel-one CH-1, which was the case assumed at thebeginning of the operation.

If after the information as to the stock numher and the range has been transmitted, and the brush BB2 is resting on the start segments shown in Fig. 2, the brush TB of the transmitting four wire distributor will have moved off the segments tdr of the ring K so that the relay TDR will be deenergized at the time that ground is applied to the segment 17-of the ring E and relay PH will not pick up. As'the brush passed over the segment 16 of the ring E, with the relays in the condition shown in Fig. 3, the channel relay CH picked up on ground over a contact 42 of the relay CS, and a contact 43 of the relay CR, and after the impulse ceased it locked over its own contact 44, the winding of the relay CS and a contact 45 of the relay PH to ground, the relay CS picking up in series with the relay-CH. At its contacts 40 and 46 the relay CH connected the line 1 to'the relay CH-2R, andthe line 2 to the relay CH--1R, so that in the next operation of the receiving distributor the stock number and range will be transmitted to the channel-two printer, and the tens, units and fractions price of the previous quotation, to the channel-one printer.

As the receiving distributor makes its second operation, receiving a second quotation, and as it transmits in succession the hundreds, tens, units stock number, and the range, it transmits the price of the first quotation over segments of the ring D. As the brush moves over segment 52 of the ring D, it connects ground from the ring F over this segment to the line 1, which is connected across a contact 26 of the tens relay TR, marked 1, if this relay is operated, to the line 2 which is connec'i ed to the segments 56, SP, 66, SP, '76, SP, ST and 81 to 85, of the ring D, and which is connected across the operated contact 40 to the relay CPI-1R, causing the relay CH--1R to pick up and control the channel-one monitor printer so that the price of the first quotation will be printed by'the channel-one monitor printer,

which printed the stock number and range of the first quotation.

As the brush continues its movement across segments 53, 54 and 55, it applies ground to the relay CH-1R, over the contacts 26 of the relays TR, marked 2, 3 and 4. In a similar manner,

the tens price is transmitted by ground on the segments 62, 63, 64 and 65, and the fractions price is transmitted by grounding the segments 73, 74 and '75.

As the four wire transmitting distributor is released for the transmission or the second quotation, ground over the channel segment CH 01 the ring J, and the operated contact 29 of the relay CS, will apply ground to the line 4 going out to the master repeating relays in the four wire system, indicating that this is a channel-two transmission. As ground is applied to the segment 16 of the ring E, after the second quotation has been received, the relay CR is operated which locks over its own contact 41 momentarily, to ground over the segment 16. This opens up the circuit for the channel relay CH so that the next stock number will be transmitted over the channel 011-1, and the price of the second quotation over the channel CH-2. The energization of the relay CR also releases the relay CS, and immediately after the brush leaves the segment 16 of the ring E the relay CR releases and the channeling and phasing relays in Fig. 3 will be in the condition shown.
